The Spicer 5-155X Universal Joint is a greaseable, outside-snap-ring U‑joint in Dana Spicer’s 1550 series, designed for driveshafts in automotive and commercial applications. It uses a 1.375-inch (1-3/8") cap size and is supplied as a greaseable joint with external snap rings for easy lubrication and maintenance. As a 5-155X variant of the Spicer 1550 family, it is compatible with standard 1-3/8" cap joints and driveshaft yokes used in medium- and heavy-duty vehicles, including trucks and equipment. This part is commonly used in driveshaft assemblies where a reliable, serviceable greaseable U‑joint of the 1550 series is specified.
